Issue with WG setup

I have setup my home server and experience an issue with the VPN, I am using two separate networks, I’ve updated it, I’ve played around with the UCP/TCP, to no avail.

What comes up on the DDNS is:

“The IP from DDNS domain resolution is not the same as the WAN IPs of the device. You need an Internet Public IP address to use the Dynamic DNS. If this router is behind NAT, you may need to set up port forward in your ISP router. If you have VPN Client enabled, please disabled “Services from GL.iNet Use VPN” in the global options.”

I have port-forwarded, set up a WG server & client, but when I click start it says: “The client is starting, please wait…”

The error log shows:

Sat Aug 12 07:28:53 2023 daemon.notice netifd: wgclient (24203): cat: can’t open ‘/tmp/run/wg_resolved_ip’: No such file or directory\nSat Aug 12 07:28:53 2023 daemon.notice netifd: Interface ‘wgclient’ is now down\nSat Aug 12 07:28:53 2023 user.notice mwan3[24304]: Execute ifdown event on interface wgclient (unknown)\nSat Aug 12 07:28:53 2023 user.notice firewall: Reloading firewall due to ifdown of wgclient ()\nSat Aug 12 07:40:53 2023 daemon.notice netifd: Interface ‘wgclient’ is setting up now\n"

Any support on how to circumvent this issue? Really need it to work asap.

Can you confirm your DDNS/DynDNS domain is able to resolve to your Internet/Public/WAN IP? Can you dig it?
